I recently acquired a broken DL4 in the hopes that I would be able to fix it. Unfortunately I haven't been able to find a fix online for the issue I'm experiencing. All the repeats sound distorted. It does this on all settings. It's especially noticeable with the looper, as it becomes more and more distorted as the loop keeps repeating. I tried resetting it, but that did not help. I tested the power supply (the regular Line6 power supply) with my multimeter, and it was putting out around 10.3 volts AC. Supposedly it should be putting out 9V AC, so I decided to try plugging it into my BBE Supa Charger. I set the dip switch correctly for a Line6 pedal, and it powered up just fine. When running from the BBE Supa Charger there was less distortion present in the repeats and the unit seemed to have more headroom. If I played softly, I could make the repeats not distort, and if I strummed hard the repeats would distort as much as they had before with the Line6 power supply. Anyone have any idea what is going on here? Links, advice, etc. would be much appreciated. Also, if you happen to be someone who fixes DL4s feel free to send me a PM.
